MySQL导入sql脚本错误:2006 - MySQL server has gone away

下面我给各位同学介绍在mysql中导入数据库时提示MySQL server has gone away问题的解决方法,如果你碰到mysql提示MySQL server has gone away错误我们可进入参考.

MySQL导入sql脚本错误:2006 - MySQL server has gone away

如一些小脚本很少报错,但最近导入一个10+M的SQL脚本,却重复报错:

Error occured at:2014-03-24 11:42:24

Line no.:85

Error Code: 2006 - MySQL server has gone away

最终找到原因,原来是MySQL导入大批量数据的时候超出了默认允许最大的数据包所以就提示2006 - MySQL server has gone away.

于是找到my.cnf,在[mysqld]加入如下代码:

1. max_allowed_packet=300M
2. wait_timeout=200000
3. interactive_timeout=200000

意思是最大允许数据包300M,等待超时/活动失效时常200000秒,重启MySQL,代码如下:

1. [root@lizhong20140323]#/etc/init.d/mysqldrestart
2. ShuttingdownMySQL....SUCCESS!
3. StartingMySQL.SUCCESS!
4. //开源软件:phpfensi.com

再重新导入,一切正常.
